Growth Conditions: Temperature: 22.0°C Duration: grown with mixed flora and fauna Protocol: ATCCNO: 30727 SPEC: This strain is distributed as a frozen stabilate. See general instructions for thawing and storage of frozen material before proceeding. Remove the frozen ampoule from the dry ice and transfer directly to a 35C water bath. The food source for this strain is Paramecium tetraurelia ATCC30303 (other strains will probably work equally well), not supplied. Empty the thawed contents of the vial into a petri dish and, if necessary, add distilled water to cover the bottom of the dish. Allow Heliophrya cells to attach to the bottom of the dish (overnight). Feed with a culture of paramecia every 7-21 days. New cultures may be established by: 1) adding a coverslip to the petri dish, allowing larvae to attach, then transferring the coverslip to another petri dish; or 2) transferring adult Heliophrya floating in surface film to a new dish by means of a wire loop.
